Here are some things I’ve learned from the Peterson Reference Guide to Owls of North America and the Caribbean by Scott Weidensaul: The Burrowing Owl is the only North American owl species where the male is larger than the female, albeit, only slightly larger. And the term is ‘non-reversed size dimorphism.’).

There are many charismatic endangered birds that capture people’s hearts and imaginations: the colossal California Condor , the evocative Red-crowned Crane , and the adorable Spoon-billed Sandpiper come to mind. Regardless of their popularity, these species and the threatened ecosystems they inhabit are equally spectacular.

(Photo by the California Forestry Association). For the past 25 years, you’ve been listed as a Threatened species. The Condor has just published research quantifying significant population declines in Washington, Oregon, and northern California. Well, now we’re getting a better idea of exactly how hard it is.

Major extinction events that are geologically instantaneous have been followed by periods of time with reduction of species or unstable habitats that last for hundreds of thousands or millions of years. There are about 10,000 species of them, after all, which is a lot for a vertebrate. Here, according to the research , there is.

You see, up to this point, let’s say 1972, perhaps 1973, I had never really been exposed to a “Threatened, or Endangered” species of any kind. The State of Oregon, in 1975 listed the bird as Threatened, and the Oregon Fish and Wildlife reaffirmed that status in 1989 under the Oregon Endangered Species Act.

Pough “with illustrations in color of every species” by Don Eckelberry, Doubleday, 1946. The National Audubon Society Birds of North America covers all species seen in mainland United States, Canada and Baja California. The press material says it covers over 800 species, so you know I had to do a count.

The last thing you want to do is ignore certain subspecies just because you’ve seen another one; in other words, skip looking for a Northern Fulmar off Maine just because you’ve seen them off California.

One North American species I am very familiar with is the Cassin’s Auklet , which ranges from the end of the Aleutian Islands to California. Unless you spend much time on their breeding islands it is probably not one of the better known species of alcid, it is small and nondescript even as auks go.

During my previous five trips to Indonesia, I only heard but never caught a glimpse of three species. Now my tally stands at four species seen and a fifth heard-only. At least in the northeastern United States, their rate of so doing is high, according to research I summarized here. I forget what its called.”

“The Purpose of Field Guides: Taxonomy vs. Utility,” co-authored with Brian Sullivan, Michael O’Brien, Chris Wood, Ian Lewington, and Richard Crossley ( Birding , November 2009) proposed a standard avian species order for field guides, apart from the ever-changing AOS taxonomic order. Species are useful handles (p. 16, below).”

Ridgway himself had 23 species, 10 subspecies, and two genera of birds named for him, including Ridgway’s Hawk.) This is probably one of the reasons Daniel Lewis,the author,turned from writing a popular biography to a history of ornithology as a science and the ornithologist as a profession.
